Automatic Color Balancing of Light-Emitting Diode-Based Lighting

摘要

Apparatus and method of color balancing LED-based lighting are provided. In one aspect, an apparatus comprises an image sensor that senses images of objects, an illumination device, and control logic. The illumination device comprises an LED that emits red light, an LED that emits green light, and an LED that emits blue light. The control logic receives an imaging signal from the image sensor related to a sensed image of a first object that is illuminated by the illumination device. The control logic controls color balancing of light emitted by the illumination device according to an optical characteristic of the image of the first object.
